So I am brand new to saltwater and I’ve had my tank running for around 1 month, It doesn’t have any corals just live rock from my LFS in Florida. As of right now I have : - Royal Gramma - 2 clowns they are pretty small maybe 1.5 inches - A diamond goby - Recently my friend had to dissemble his tank so I now also have a Hoeven’s wrasse. Is my tank over stocked? I have a 20 gallon with lots of live rock around 13 pounds. I plan to upgrade to a 50 gallon in around 6-12 months when I move out of my college dorm.
